RNA

* More ID property support. What was already possible was showing
  ID properties as RNA properties. Now it is possible to define
  RNA properties and have an ID property automatically created the
  first time it is set (if not set it retuns the default).

* Added support for defining RNA structs and properties at runtime.
  This is useful for python and plugins, and could also be used
  for operators, not sure yet what is best there, they could be done
  in preprocess for speed, but not sure how to do that while keeping
  operator registration a single function.

* Added quick functions to get/set properties based on names, to be
  used for operators.

* Added some simple support for inheritance, was already doing this
  but having it as a feature simplifies things. Two things were added
  for this: when defining a struct you can give a 'from' struct whose
  properties will be copied, and structs like ID, operator, modifier,
  can define a refine callback that will return the more specific type
  of the struct like ID -> Object, Mesh, .. .

* Added simple windowmanager wrap with only the registered operators
  list, used for testing RNA for operators.
